ADNACO-S3B USB 3.0/2.0 OVER FIBER OPTIC EXTENSION SYSTEM

Adnaco Remote host USB system is a PCIe to USB extender.  There is a  PCIe card that provides two USB 3.0 ports extended remotely by Fiber Optic Cables.  

In an audio PC, this removes the USB interface from the noisy PC motherboard.  For better audio, use a high-quality power supply on the endpoint.

I have found that this interface provides significantly improved sound quality vs. the USB ports on a typical PC Motherboard.

Adnaco also sells a four-port card that can extend to multiple endpoints.  Several members of the forum have tested different SFP+ and fiber options to improve the sound even further.

Very interesting product. Would be interesting to hear how it performs in comparison to the Sonore OpticalModule+OpticalRendu combination.

If I understand correctly the Sonore OpticalRendu and OpticalModule are Ethernet based.  The OpticalRendu has optical Ethernet input (via the SFP) and USB-Audio output, and the OpticalModule uses the SFP fiber optic transceiver for Ethernet input/output with the RJ45 connector also as input/output.

The Adnaco is USB based, running the USB signal via the optical cable.  

So the similarity between them, is they booth run the signal vial SFP optical modules, and the difference is the Adnaco is USB based while the Sonore is Ethernet based.   

Is this correct?

As I noted above the ADNACO is a PCIe bus extender. One of the applications is PCIe->USB.  They also have other applications.

 

 We are using the ADNACO  to get the computing noise away from the USB ports and using good DC power at the endpoints to not re-introduce noise.  You can use the extended USB port for DAC, or USB Ethernet, or keyboard and mouse if you want!..  

 

The selection of the SFP+ (10 Gbits) transceivers and Fiber Optic cable is another set of variables in building these systems.  There have been a few threads on the forum discussing ADNACO.  

 

The Sonore systemOptique  is a particular selection of optical cables and SFP transceivers that are Optical Ethernet IP devices. They have multiple devices that use their optical ethernet.  There has been extensive discussion on the forum around optical networks and Ethernet in general.

 

Here is my blog post on SFP devices

Had a look at the Adnaco products.  The USB remote uses the ten year old NEC USB3 controller, the same as the original J Cat card.  Adnaco's site doesn't say how this controller is clocked.  The upsides are isolation by optical cable and  powering the remote with a 5V supply of choice.  A better option may be to use the Adnaco RT4 PCIE card and populate it with a H1A optical card and a more recent USB card.  The H1A will require 3.3V, the USB card, 3.3, 5V and possibly 12V.  The J Cat and Pink Faun cards are a simpler but more expensive solution.

Thanks for the information. I do not find the card installed in the computer a simpler solution, it is different.  Also the computer has to be next to the DAC, etc.  You still need an extra LPS rail for the card in the server.  

 

My server is in the basement with three remotes in use: one for network, one for headphone system and one for the living room.  
In my example the Hugo 2 endpoint and an ADNACO are powered by an Allo Shanti dual 5V supply.

 

All things are tradeoffs.  In my mind you cannot tell what sounds better unless you test them yourself!
